Lesson Learned from a Case of Radioactive Contamination

Abstract

A radiochemistry laboratory presents potential radiological hazards due to the handling of multiple radionuclides with various half-lives and modes of radiation emission. To minimize these hazards, appropriate safety management and radiation protection strategies should be in place. The radiochemistry laboratory at Soochow University is one such workplace that handles therapeutic radionuclides, fission products, and actinides in liquid, solid, and gas forms. This work highlights the significance of using safety precautions and radiation protection strategies before conducting experiments in such laboratories. The practical knowledge gained from a case of radioactive contamination is discussed to provide valuable experience for safely conducting radiochemistry experiments.

“…In this context, 129 I and 131 I are the most important radioiodine isotopes. The former ( 129 I) is associated with a very long half-life (>15 million years) than the later ( t 1/2 of 131 I is only ∼8 days). , However, significantly more energetic γ rays are emitted during the radioactive decay of 131 I (∼364 keV) than that of 129 I (∼30 keV) . The element, iodine, is volatile in nature, dissolves in both aqueous and nonaqueous solvents, and has a tendency to accumulate in the thyroid gland of animals (including humans) .…”
